In this study, electrochemical corrosion and wear experiments were conducted to clarify the role of cryogenic treatment on microstructural morphology resistance high-manganese austenitic steel. Heat solution (950 °C) annealing (500 °C 600 performed hot-rolled specimens. Cryogenic was applied hot-rolled, + heat treated is a practical technology for eliminating strip specimens improves heat-treated However, it plays different tested related with production process. The mechanism differs due...
Retained austenite (RA) transformation and its role in the mechanical properties of three low-carbon micro-alloyed quenching partitioning (Q&P) steels was investigated utilizing situ tensile tests electron microscopy. Meanwhile, RA’s strain-induced martensite (SIMT) analyzed discussed terms strengthening mechanism. The results show that ductility Q&P relies on size morphology RA. In addition, both affect or thermostability. Dislocation density carbon trapping should be considered...
A cyclic wet/dry accelerated corrosion test was used to compare the behavior of medium-Mn steel and Q345 steel. In terms scanning electron microscope (SEM), using X-ray diffraction (XRD), probe microanalysis (EPMA), photoelectron spectroscopy (XPS), analysis process, results showed that did not exhibit higher resistance than due greater content Mn-rich compounds in rust layer. Moreover, effect a small amount anti-corrosion elements medium-manganese can regulate rate. The conceptual model...
The construction of heavy polar icebreakers is usually done with special hull steels, which require comprehensive properties such as good low-temperature toughness, high strength, and superior fatigue resistance. Reasonable satisfactory heat treatments should be investigated applied to acquire the required strength since this deemed an effective approach ameliorate combined high-strength steels. Regarding this, present study specifically explores effects different laboratory-based quenching...
This work used the neutral salt spray test to investigate effects of microstructure and alloy elements on corrosion process medium manganese steel by analyzing microstructure, corros...
Effect of thermal treatment on the evolution delta ferrite was studied in 11Cr–3Co–2.3W steel. Ferrite-forming alloy elements promoted formation during thermo-mechanical processing. The results JMatPro and chromium equivalent calculations indicated that steel partially contained ferrite. Cr W were segregated in/around Delta had a bamboo-type morphology it MX-type carbonitrides inside Laves phase at interface between martensite. On annealing, dissolved especially early stage annealing. After...
AbstractAbstractDynamic recrystallisation behaviour of an as cast 0Cr18Ni9Ti stainless steel during hot deformation was investigated by compression test at a temperature range 950–1200°C and strain rate 5 × 10-3–1 10-1 s-1. Change austenite grain size owing to dynamic also studied microstructural observation. The experimental results showed that the conditions, such temperature, strain, determine for steel, dynamically recrystallised is determined conditions independent strain.
Microcantilevers were machined from a single γ(TiAl)-α2(Ti3Al) lamellae colony of polycrystalline commercial Ti-45Al-2Mn-2Nb sample using the focussed ion beam. The long axis microcantilevers is perpendicular to lamellar interface with notch prepared in same γ lamella. Bending test results demonstrated good repeatability and fracture stress intensity factor individual lamella was measured be 3.1 ± 0.2 MPa m1/2. (1¯1¯1)[1¯1¯2¯] twinning ahead (crack) tip plays key role crack initiation. TEM...
The microstructure of Cr–Mn–Ni–N stainless steel is regulated by a combination cold deformation and subsequent martensite reversed annealing. yield strength tensile the tested are greatly improved to 1220 1357 MPa, respectively, conventional heavy rolling (66% thickness reduction) annealing process (750 °C for 5 min) relative those before (austenized state); at same time, total elongation keeps an appropriate value. results show that grain refinement strengthening acts as primary factor...
In order to obtain the good match between yield strength and low-temperature toughness, short-time partial austenitization (SPA) process was employed for V/Mo-bearing 0.22C–5.24Mn steel. The initial microstructure after intercritical tempering dual-phase ferrite reversed austenite (RA), while final consisted of ferrite, RA, secondary martensite (SM) being subjected SPA process. (V, Mo)C with disclike morphology mainly precipitated during tempering, aspect ratio particles decreased, leading...
